Question about Drills

Open Question

I have a CSB 850 2 Ret drill. When I try to start it the motor seems to be straining and the chuck will not turn. Sometimes if I start it very slowly the it will pick up speed and will be OK until I stop it and then I have the problem starting it again.

The chuck wont tighten

Sometimes the chucks jam when opened all the way. A firm hand and a quick **** of the chuck sleve will release it sometimes.

On my BOSCH CSB 470-RLE 470w electric drill the chuck is slipping i can hold it in my hand and it wont move

It is a spring loaded hammer drill. You need to push the chuck down just a bit for it to engage the clutch. If it is still slipping then either the clutch pieces (items 23 and 32) are worn or item 32 is spinning freely on the spindle shaft. Here is a parts diagram.

I have just purchased a Makita 8391DWPETK 18V Cordless Combi Drill - how do i actually put a drill bit in? Do I need to take off the plastic ring?

The large black part of the chuck should turn left and right to extend (close) and retract (open) the three chuck teeth that hold the bit in place. Turn the chuck to open it far enough to get your bit fully in the chuck then turn it closed to hold the bit in. When the teeth make contact turn the chuck a bit further to get it tight enough that the bit won't slip. When you get used to it, sometimes it's easier to hold the chuck lightly and turn it by lightly squeezing the trigger to turn the chuck with the drill motor.

Cant get the bit out of my cordless bosch drill, chuck seem to be jamed and wont open

what you can try is to spray penetrating fluid on the chuck collar, jaws. Next if you have a GOOD pair of gloves hold the collar and then using the drill motor try and loosen the chuck. If you have a vise with a pair of soft jaws without clamping too tight you can try the same thing. The main purpose is to let the drill torque loosen the chuck collar to release the bit.

Chuck is very hard to adjust

Try lubrication, and check that the retaining screw, down inside, has not come loose. failing all of that, replace the chuck.

Need to remove the chuck to access the adj. clutch

first remove the chuck ret screw it is LH threads, shift the tool to the low position and the clutch to drill only. Find a bent handle allen wrench about the chuck capacity and lock the smaller end into the jaws, next put the chuck on a workbench or block of wood with the long portion at about a 30 degree handle so you can hit it counter clockwise and strike it with a hammer, it might take a few hits but it will come loose.

Chuck Shaft becoming detached from drill motor

Many times there is a allen head screw in the center of the chuck bottom that screws into the shaft of the drill if this screw is missing the chuck will unscrew off the shaft. Many times depending on the size of the drill it is a 10/32 allen screw about 3/4" long that screws into the shaft thru the open end of the chuck.. Sometimes it is a Left handed thread.Check the illustrated parts breakdown for the drill to get the correct part. Hope that helps
